We have two of these string lights. After 12 months the bulbs are full of water. It's not from rain or snow but from condensation (Buffalo NY) Because they were full of water half of the lights on each string got very dim and burned out. We have ordered 3 different kinds of bulbs but none of them work. They all look identical to the original ones and all 3 are a different wattage. One of the replacement sets is the same wattage of the original ones. If we put back a wet bulb it turns on so we know the socket is good. I will be buying better ones next time.They have held up very well. Just not as bright as I thought they would be. But for the price I am not complaining. They provide a nice addition to our patio.I love these. Will buy again! Easy to run remotely from my phone. The lighting is perfect on my 3 season porch!They have lasted me so long, they have endured rain and lots of heatThese have been awesome to line our fence in our backyard. I needed more light when I let my dogs out at night and these helped so much. We don’t have any outlets so I needed solar power. These are great!I had problems with this product from the start. Called the Amazon to notify. Amazon put me in contact with seller. Worked with them on the phone several times. Would not work/ light up. They told me it could be this, or this or this. Very frustrating trying everything they said. Eventually I realized there was a bad wire in the connection so I cut it and rewired it myself. Now as I discovered when I used it for a party about a quarter of the weather proof/ waterproof lights have water in them. I don't think I have owned this longer than a year. Do not recommend this product. Do not know how to get back in contact with company. Will have to call Amazon again. Too much trouble.Nice lights, bright and fun. Solar panels are excellent too. However, I'm a bit worried about the fact that some of the bulbs seem to be taking on water after it rains. The good news is that all the bulbs are still working and I have not had to replace any, but I still do worry about them shorting out eventually. But so far so good...When we bought these we bought them because they look great. We didn’t know at the time that they were supposed to be able to sync with your Alexa so you can turn them on and off. I’ve tried multiple times and can’t seem to get them in the sync. But that’s not what we bought them for.Hola: llegaron tres bombillas que no prenden y solo una de repuesto.Cómo ahí que? Podrán enviarme esas tres? Se los agradecería.Además, creo que también falto el complemento para fijar la foto celda.Por lo demás, todo está bien.No sirvió, la cargue via usb y solar y nunca funcionó, adicionalmente a esto pasó el tiempo y no pude devolverlo. Pésimo
